Abstract

There is a scenario of strong field quantum electrodynamics where electron-positron pairs copropagating with an extremely intense laser mediate the continuous transformation of laser photons into directional gamma rays. This is made possible by a quasi-guiding equilibrium wherein the pairs are partially confined to the region of high intensity by quantum recoil. The laser parameters required to access this regime are far in advance of the current state of the art, but are made more plausible by operating at short wavelengths. Argon fluoride lasers are a possible route to accessing this regime.
